Dear expert,
I have some ALSA questions please:
-
Why codec driver of ASOC are always I2C based ?, is codec driver role is only control of audio hardware(set/reset registers only)? -
There should be three drivers : machine driver, platform driver and codec driver , all of them have .probe and . remove , what is relation between all the probes? removes ? -
As far I know McBSP is source of audio coming from host and I2C/ McBSP have no direct relation so why we connect platform driver (McBSP) with codec driver(I2C) Via DAI ? -
When calling snd_pcm_open from userspace which kernel API is called ? snd_pcm_lib_ioctl or snd_stm_spdif_player_open ? if snd_stm_spdif_player_open so when called snd_pcm_lib_ioctl ? -
How ALSA KERNELAPI is connected to ALSA SOC CORE, via which calls/mechanism ?
Thanks q lot for your great help
